This part number convention (26-87-40-47-00040) encodes the series, tube OD, and sequence information in the part number itself, a convention used by several European driveshaft manufacturers.A 3.875mm wall on a 100mm OD tube is a heavy wall specification. Thin-wall tubes for this OD are typically 2.5-3mm; a 3.875mm wall significantly increases the section modulus and torsional stiffness of the shaft. This is used on applications where the shaft must handle high torque or where the tube length approaches the critical speed limit for the OD.SpecificationMetric ValuePart Number2687404700040Series68740 / 2040Tube OD100mmTube Wall3.875mmButt Diameter92.25mmCL-to-Weld100mmMaterialSteelThe 92.25mm butt diameter is the yoke pilot that seats inside the tube bore. For 100mm OD x 3.875mm wall, the ID is approximately 92.25mm, making this a close-tolerance slip fit. Confirm your tube’s actual bore before ordering. Weld procedures for heavy-wall metric tubes should follow the tube manufacturer’s specifications for preheat and filler selection.See weld yokes.

Cap diameter of 1.062″ makes it immediately identifiable versus the 1.188″ caps of the 1350 and 1410 series. The 2-28-557 fits 3.250″ OD tubing, a diameter common on full-size pickup and van one-piece rear driveshafts.The 0.065″ tube wall on a 3.250″ OD shaft gives adequate stiffness for moderate-length, low-torque shafts. For applications where the shaft runs near its critical speed limit or where significant torque is transmitted, a 0.083″ wall is recommended. The 0.065″ wall is acceptable for OEM-style replacement on shafts up to approximately 48″ in length at normal highway speeds.SpecValuePart Number2-28-557Series1310Tube OD3.250″Tube Wall0.065″Butt Diameter3.130″CL-to-Weld1.688″MaterialSteelThe butt diameter of 3.130″ is 0.120″ smaller than the tube OD, which is the standard 0.060″ per side clearance for fitting inside the tube.

The 2826-101 is the weld tube yoke for this series, specified for the Mercedes front driveshaft application.The 1.000″ OD tube with 0.120″ wall is a heavy-wall-to-diameter ratio. Tube OD of 1.000″ with 0.120″ wall leaves only 0.760″ inner diameter. This thick wall relative to the OD results in high torsional stiffness in a very small package, appropriate for the compact front driveshaft on 4WD and AWD Mercedes vehicles where shaft length is short and the U-joint operates at higher than normal angles.Part Number: 2826-101Series: 1751Application: Mercedes Front DriveshaftTube OD: 1.000″Tube Wall: 0.120″Butt Diameter: 0.967″CL-to-Weld: 1.675″Material: SteelThe 0.967″ butt diameter fits inside the 1.000″ OD tube. Actual tube bore will be approximately 0.760″ ID for 0.120″ wall, so this yoke butt is machined to fit the tube OD’s outer face as a butt weld, not an inside-pilot fit.

Critical speed rises with tube diameter and drops with shaft length, so a 4-inch tube on a long shaft can run at the same speed that would cause whip in a 3-inch tube. The 3-28-417 brings the 1350 series U-joint into this large-tube application.The 1350 series handles the torque loads typical of 3/4-ton and 1-ton trucks but the 4.000″ tube is an unusual combination, seen primarily in custom and performance builds where shaft length forces the diameter up for critical speed compliance. This yoke will not fit standard 3.000″ or 3.500″ tube.Part Number: 3-28-417Series: 1350Tube OD: 4.000″Tube Wall: 0.083″Butt Diameter: 3.844″CL-to-Weld: 1.688″Material: SteelThe 3.844″ butt diameter (0.156″ smaller than the tube OD) is the yoke’s machine-turned pilot that fits inside the tube bore. Confirm your tube’s actual ID before ordering: 4.000″ OD x 0.083″ wall yields a nominal 3.834″ ID, so the butt should slip in with 0.002″-0.005″ clearance for proper fit and weld concentricity.View all weld yokes.

Cap diameter is 1.188″, same as 1410, but with shorter trunnion length. The 3-28-137 is a weld tube yoke for 3.000″ OD x 0.065″ wall tube.Note the tube wall specification: 0.065″ is thinner than the more common 0.083″ used on most 3.000″ OD light truck driveshafts. This thinner wall reduces rotating mass and is appropriate for applications where the tube length is short and torsional stability is not a concern. Longer shafts or high-torque applications should use 0.083″ wall or thicker.SpecificationValuePart Number3-28-137Series1350Tube OD3.000″Tube Wall0.065″Butt Diameter2.875″CL-to-Weld2.030″MaterialSteelThe 2.030″ CL-to-weld is slightly longer than the common 1.688″ seen on many 1350 weld yokes, giving more weld face area at the tube interface.

It is found on certain import light trucks, small RWD vehicles, and specialty drivetrain applications where a 1310 is oversized but 1210 torque capacity is insufficient. The 1226-17 is the weld tube yoke for this series.The tube dimension of 1.775″ OD x 0.065″ wall is a smaller-than-standard specification. Most domestic light truck tubes run 2.000″ OD or larger. This size appears on smaller Japanese-platform driveshafts and some early compact trucks. The 0.065″ wall is thinner than the 0.083″ standard and is appropriate for light torque loads only.Part Number: 1226-17Series: 1251Tube OD: 1.775″Tube Wall: 0.065″Butt Diameter: 1.667″CL-to-Weld: 1.750″Material: SteelThe 1.750″ CL-to-weld is relatively short, meaning the yoke body is compact. Confirm this does not create a driveshaft that is too short for your application once the tube is welded to both ends. Butt diameter of 1.667″ should match your tube bore within 0.003″ for a proper press-and-weld fit.See all weld yokes.

| | 3-28-57-2 | 3-28-57-2 UDS 1350 Series Steel Weld Yoke — 2.750″×0.065″ Tube, 2.625″ Butt… Show more (+) 3-28-57-2 UDS 1350 Series Steel Weld Yoke — 2.750″×0.065″ Tube, 2.625″ Butt Dia, 2.000″ CJ-to-WeldThe 3-28-57-2 is a UDS 1350 series steel tube weld yoke machined for 2.750-inch OD driveshaft tubing with a 0.065-inch wall thickness. The yoke becomes a permanent part of the driveshaft assembly once welded; the driveshaft tube butts against the 2.625-inch shoulder diameter and is MIG or TIG welded in place, establishing the rigid connection between the tube and the 1350 series yoke ears. The U-joint centerline-to-weld-face dimension is 2.000 inches, which determines the yoke’s contribution to the total driveshaft collapsed length when calculating assembly geometry. Research identifies the Neapco N3-28-57-2 as the direct equivalent, with additional cross-references: 7834453, R3-28-1107, P7834453, and 74084453.The tube specification of 2.750×0.065 describes two distinct dimensions that must both be correct before welding. The 2.750-inch OD is the outside diameter of the tube wall; this must match the bore preparation of the yoke’s weld end, which is machined to receive 2.750-inch tube. A tube with a larger OD will not seat against the butt shoulder; a tube with a smaller OD will produce an off-center joint with a gap on one side that cannot be corrected with weld fill. The 0.065-inch wall thickness affects the depth of the weld bevel — thin-wall tubing (0.065-inch) requires a different heat input and bevel angle than heavier wall (0.083-inch or 0.120-inch) tube; verify wall thickness with calipers before cutting the weld prep. The butt diameter of 2.625 inches is the shoulder OD at the yoke weld end; the tube butts square against this shoulder, and the weld is laid in the groove between the tube end face and the yoke shoulder. The 1350 series yoke ears accept 1350 U-joints: 1.188-inch cap diameter on a 3.625-inch span. A 1310 cap at 1.062 inches will spin freely inside the 1350 bore and produce immediate joint failure; do not mix series at the U-joint bore.SpecificationsPart Number: 3-28-57-2Brand: UDSSeries: 1350Material: SteelTube OD × Wall Thickness: 2.750″ × 0.065″Butt Diameter: 2.625″Center U-Joint to Weld (CJ-to-Weld): 2.000″Cross-References: Neapco N3-28-57-2, 7834453, R3-28-1107, P7834453, 74084453Fitment & Installation NotesBefore ordering the 3-28-57-2, confirm the driveshaft tube OD is 2.750 inches and wall thickness is 0.065 inches. Do not assume wall thickness from OD measurement alone — 2.750-inch OD tubing is available in multiple wall specs (0.065″, 0.083″, 0.120″) and the yoke bore and weld prep are specific to the 0.065-inch wall. Measure wall thickness with a micrometer at the cut end of the tube, not at a bent or swaged section. After confirming tube dimensions, square-cut the tube end, deburr both the ID and OD edge, and clean the mating surface to bare metal before welding. An off-square cut produces a weld joint with variable gap, which concentrates stress at the narrow side and creates a balance problem after the assembly is spun.The 1350 series places the 3-28-57-2 in the mid-range of the Spicer torque hierarchy, above the 1310 and 1330 but below the 1410 and 1480. The 1350 is the standard rating for 3/4-ton pickup trucks, full-size SUVs, and light commercial applications — it is the most common series used in custom driveshaft fabrication for these platforms. The Neapco N3-28-57-2 cross-reference (also listed as N3-28-57-2 at Drivetrain America for the 2.750×0.065 specification) and the additional cross-references 7834453 and R3-28-1107 confirm broad aftermarket availability for this combination. When using this yoke as part of a balance-quality shaft, ensure the weld joint is concentric — the yoke bore must run true to the tube centerline within 0.005 inches total indicated runout after welding, or the assembly will not balance to acceptable vibration limits. Use the 3-28-57-2 only with 1350 series U-joints to maintain series integrity.Explore related Weld Yoke components including 1350 series U-joints and driveshaft tubing.

The tradeoff is weld technique — aluminum requires TIG welding with proper pre-heat and filler selection; MIG welds used on steel yokes are not appropriate here. The weld quality is more sensitive to operator skill than a steel joint, but a correctly executed aluminum weld on a balanced shaft is fully service-worthy.Alternate part number: ATY1350-400.

It sits between 1310 and 1350 in torque capacity but uses its own distinct U-joint with different cap dimensions than either standard Spicer series. This matters because a 3R U-joint will not interchange with a 1310 or 1350 joint — if you’re sourcing U-joints for a 3R driveshaft, they must be specifically catalogued as 3R series.The 3R-28-437 is the weld yoke for this series: it welds onto a 3.000-inch OD tube with 0.083-inch wall thickness. Butt diameter is 2.844 inches — the outer dimension of the weld joint face. Center-of-U-joint to weld face runs 1.875 inches. Steel construction. Before welding, confirm tube OD and wall: a tube with 3.000-inch OD but 0.120-inch wall (common upgrade) will not seat correctly in this yoke.Part Number: 3R-28-437Brand: UDSSeries: 3R (GM-specific)Tube: 3.000″ OD x 0.083″ wallButt Diameter: 2.844″CJ to Weld: 1.875″Material: SteelIf upgrading this driveshaft assembly to a more common series, note that the 3R yoke ears and U-joints must all change together — you cannot mix 3R and 1310/1350 components.

This yoke is welded to a cut driveshaft tube and becomes a permanent structural component of the assembled driveshaft. The 1350 series designation specifies the U-joint cap bore: 1.188-inch diameter caps fit the yoke ears. The butt diameter at the weld joint is 3.855 inches; center U-joint to weld dimension is 2.125 inches.The aluminum T6061 construction of 3526-403A reduces rotating assembly weight compared to steel weld yokes — a direct benefit in high-performance and weight-sensitive driveshaft builds. T6061 is a heat-treated aluminum alloy with adequate yield strength for 1350 series torque capacity in the intended application range. However, aluminum weld yokes are not interchangeable with steel yokes in all applications: the weld process for aluminum (TIG, typically) differs from steel (MIG/TIG), and the thermal characteristics of aluminum require specific preparation and post-weld handling. Confirm your driveshaft fabricator has experience welding aluminum yokes to aluminum tube — welding an aluminum yoke to a steel tube is not a recommended practice. The 4.000-inch tube OD is a large-diameter tube, common in high-performance custom driveshaft builds where the larger diameter raises the critical speed threshold. The 0.083-inch wall is a standard wall thickness for 4.000-inch aluminum tubing; do not substitute 4.000×0.065 or 4.000×0.120 tube without confirming the yoke butt bore is machined to the correct OD for the wall to fully engage the weld prep.SpecificationsPart Number: 3526-403ABrand: UDSSeries: 1350Material: Aluminum T6061Tube Diameter x Wall: 4.000″ x 0.083″Butt Diameter: 3.855″Center U-Joint to Weld: 2.125″U-Joint Cap Diameter (1350 series): 1.188″Fitment & Installation NotesConfirm the driveshaft tube is 4.000-inch OD by 0.083-inch wall before ordering 3526-403A. The butt bore of this yoke is machined to fit the 4.000-inch OD; a tube with a different OD will not seat concentrically in the butt bore, and any resulting eccentricity in the weld joint will cause a balance issue that cannot be fully corrected by static or dynamic balancing. The 3.855-inch butt diameter is the outer diameter of the yoke at the weld joint — this is the reference for fitup and gap measurement before welding.The 1350 series U-joint yoke ears on 3526-403A accept 1.188-inch cap diameter U-joints in OSR (outside snap ring) retention unless otherwise specified. Confirm snap ring groove style on the mating U-joint. The 1350 series is common in 3/4-ton truck rear driveshafts, modified 4WD front driveshafts, and high-performance custom builds. Aluminum weld yokes in 1350 series are typically chosen for racing or performance builds where driveshaft weight reduction is a priority — the 3526-403A provides this while maintaining 1350 series torque capacity in the yoke geometry.After welding, the driveshaft assembly must be dynamically balanced. Aluminum responds differently than steel during the balancing process — balance weights must be compatible with aluminum (steel weights welded to aluminum can cause galvanic corrosion at the joint over time). Confirm with your balancing facility that they can accommodate 4.000-inch aluminum driveshafts. The center U-joint to weld dimension of 2.125 inches is the distance from the U-joint cross centerline to the weld joint — verify this is compatible with your overall driveshaft length calculation before cutting the tube.Explore related weld yoke components including 1350 series steel weld yokes and other tube OD configurations.

On stock-height vehicles, the shorter 3R82-321 is typically correct. On lifted trucks with aftermarket suspension travel, the longer neck of 3R82-322 is required to maintain acceptable joint angles at full droop. Installing the wrong variant produces a 2x driveline frequency vibration that is often misdiagnosed as a wheel balance issue.No boot cap is listed for this part number — inspect the transfer case output seal each time the shaft is removed. A worn output seal will allow gear oil to contaminate the spline, breaking down the grease and initiating pitting corrosion on the spline flanks.

This external-splined shaft is configured as a transmission yoke, meaning it slides directly into the tail housing rather than bolting to a separate output flange. The 9.055" C/L-to-end dimension suits medium-wheelbase trucks where the front driveshaft requires a longer slip section. Pair with a 1410 U-joint and verify the tail housing seal bore accepts this shaft’s OD before installation. Boot cap 40123472 (OEM Neapco/Dana cross-reference) keeps dirt and water out of the spline interface — always install with the driveshaft pointed downward so grease gravity-feeds into the spline roots.

Confusing pilot diameter with bolt circle is a common error that results in a loose fit and vibration at operating speed. Cross-reference with Spicer 5-1310X or Dana 1310 series U-joints when servicing the driveline.The 32-spline x 1.378" profile is standard for many light-truck and medium-duty transfer case outputs. Spline length of 3.500" provides adequate engagement depth for a secure press-fit or slip interface. Boot cap 3R18-321 protects the spline from contamination — replace it any time the shaft is pulled from the housing. The 1310 series U-joint cap diameter is 1.062", placing it in the lighter end of the Spicer strength range.Verify the transmission yoke bore and seal diameter match this shaft’s hub before assembly. A mismatched seal OD will allow transmission fluid to migrate into the driveline housing, contaminating the spline grease and causing accelerated wear.

Attempting normal U-joint removal on a staked configuration without the correct press tooling will damage the yoke ears.The 1182-241 is an Infiniti front driveshaft yoke shaft (9951-22 series) where the U-joint caps are staked rather than retained by snap rings. The 0.972" spline diameter, 24-spline count, and 5.130" CL-to-end differ slightly from the 1182-242 (non-staked, 4.461" CL-to-end). Staked U-joints require press-out tooling for disassembly — pressing in the wrong direction scores the cap bore. When replacing this stub shaft, replace the entire yoke shaft assembly rather than attempting to service the individual staked joint.

The 9951-22 series is a foreign-application designation for Infiniti/Nissan AWD front shaft components. The 0.972" spline diameter and 24-spline count are specific to this application.Q: Is 1182-242 interchangeable with 1182-241?A: No. The 1182-242 has 4.461" CL-to-end and 1.575" spline engagement vs the 1182-241 (5.130" CL-to-end, 1.693" engagement, staked joints). The staked-joint note on 1182-241 means that shaft also requires special disassembly tooling. Use 1182-242 for standard replaceable joint configurations.Q: What are the dimensions to confirm?A: 0.972" spline dia, 24 splines, 1.575" engagement, 4.461" CL-to-end. This stub shaft is specific to Infiniti front shaft applications.
